We conclude that RBC cholinesterase inhibition is the critical effect, that human studies form the best choice of species—supported by a wealth of experimental animal data, that a NOAEL of 0.1 mg/kg/day is the most appropriate point of departure, and that a 10-fold factor for within human variability is sufficient to characterize the overall uncertainty in this rather large database. The high dose in the subsequent 2-year study was 10 mg/kg/day, with lower doses of 0, 0.05, 0.1, or 1.0 mg/kg/day chosen to define dose-response patterns. Chlorpyrifos is normally supplied as a 23.5% or 50% liquid concentrate. After a thorough review of the experimental animal literature, it was determined that the chlorpyrifos repeated-exposure RfD based on application of a 100-fold uncertainty factor on the no observed adverse effects level (NOAEL) for brain cholinesterase inhibition or on a 10-fold uncertainty factor on the NOAEL for erythrocyte cholinesterase inhibition is 0.01 mg/kg/d.
